CROSS-REFERENCE TO RELATED APPLICATIONS

Not applicable.

BACKGROUND OF THE INVENTION

Frequently, canoe users find that a singled bladed canoe paddle is less effective than would be a doubled bladed kayak paddle. Users may wish to convert between canoe paddles and a kayak paddle for a number of reasons. For example, the user may be paddling alone, windy conditions may arise, or the user's partner tires out or wants to do something else like take pictures. However, current methods of allowing a canoeist to choose between canoe paddles and kayak paddles are less than satisfactory for a number of reasons.

For example, there are other paddles that convert from single to double by using a push button and spring lock. These paddles must be purchased with the spring lock. This makes this solution both inapplicable for existing canoe paddles and also dramatically increases the cost of the canoe paddles.

Alternatively, some canoeists take both single and double bladed paddles in the canoe with them. Storing the double bladed paddle while paddling with the single blade is very bothersome as is storing the single bladed paddles while paddling with the double bladed paddle. Space is at a premium in the canoe and the extra paddles are a waste that is often more trouble than it is worth.

Accordingly, there is a need in the art for an inexpensive device which can be used to secure two canoe paddles in a configuration that they can be used as a single kayak paddle. Further, there is a need in the art for the device to be as small as possible, to preserve space within the canoe. Moreover, there is a need in the art for the device to be simple to use.

DETAILED DESCRIPTION OF SOME EXAMPLE EMBODIMENTS

Reference will now be made to the figures wherein like structures will be provided with like reference designations. It is understood that the figures are diagrammatic and schematic representations of some embodiments of the invention, and are not limiting of the present invention, nor are they necessarily drawn to scale.

FIG. 1 illustrates an example of a paddle converter 100. The paddle converter 100 can be used to secure two singled bladed canoe paddles to form a single twin bladed kayak paddle. Users may wish to convert between canoe paddles and a kayak paddle for a number of reasons. For example, the user may be paddling alone, windy conditions may arise, or the user's partner tires out or wants to do something else like take pictures.

Canoe paddles include the following parts:

• • Grip—The handle formed on the top of the paddle shaft;
  • Shaft—The section of the paddle between the grip and paddle blade;
  • Throat—The transition point between the shaft and paddle blade;
  • Paddle Blade—The portion of the paddle that contacts the water;
  • Powerface—The face of the paddle blade that contacts the water during a forward stroke;
  • Backface—The face of the paddle blade opposite of the powerface; and
  • Tip—The extreme end of the paddle blade

In addition, canoe paddles can include the following configurations:

• • Straight Shaft Paddles—Canoeists that paddle from a kneeling position prefer these paddles and they are the most commonly produced paddles. Paddling can be accomplished with either face of the paddle blade; and
  • Bent Shaft Paddles—These paddles have a bend at the shaft throat of 10 to 15 degrees (i.e., the major axis of the shaft and the blade are not in line with one another) making them easier to use for seated paddlers. Bent shaft paddles can only be used with their bend angle facing forward. Forward movement is more efficient, but turning strokes are more difficult with these paddles.

Canoe paddles and kayak paddles have a number of different characteristics. These characteristics may be advantageous in some settings and detrimental in others. Therefore, allowing a user to change from a canoe paddle to a kayak paddle allows the user to take advantage of desired characteristics when conditions dictate.

Paddles commonly used in canoes consist of a wooden, fiberglass, carbon fiber or metal rod (the shaft) with a handle on one end and a rigid sheet (the blade) on the other end. Paddles for use in kayaks are longer, with a blade on each end; they are handled from the middle of the shaft. Kayak paddles having blades in the same plane (when viewed down the shaft) are called “un-feathered.” Paddles with blades in different planes are called “feathered”. Feathered paddles are measured by the degree of feather, such as 30, 45, or even 90 degrees. The shaft may be straight or may have a ‘crank’ added with the aim of making the paddle more comfortable and reducing the strain on the user's wrist. Because both canoe and kayak paddle are not supported by the boat, paddles made of lighter materials are desired; it is not uncommon for a kayak paddle to be two pounds (32 ounces) or less in weight and very expensive paddles can be as light as 22 ounces.

Cheaper paddles have an aluminum shaft while more expensive ones use a lighter fiberglass or carbon fiber shaft. Some paddles have a smaller diameter shaft for people with smaller hands. Paddle length varies with a longer paddle being better suited for stronger people, taller people, and people using the paddle in a wider kayak. Blades also vary in size and shape. A blade with a larger surface area may be desirable for a strong person with good shoulder joints, but tiring for a weaker person or a person with weaker shoulder joints.

A kayak paddle is held with two hands, some distance apart from each other with the hands equally spaced from the center point of the shaft. For normal use, it is drawn through the water from front (bow) to back (stern) to drive the boat forward. The two blades of a kayak paddle are dipped alternately on either side of the kayak. In contrast, a canoe paddle is held with two hands, one on the end (which usually has a grip) and the second hand on the shaft. The blade is drawn through the water from front (bow) to back (stern) to drive the boat forward. The canoe is then lifted, passed over the boat and placed in the water on the opposite side of the canoe, where the driving motion is repeated.

FIG. 1 shows that the paddle converter 100 can include a body 102. The body 102 is configured to structurally support the canoe paddles when secured to one another forming a kayak paddle. I.e., the body 102 provides a structural intermediary between the canoe paddles, converting them into a kayak paddle. In addition, the body 102 can include a twist or curve that allows the paddles to be feathered relative to one another if the user so desires. Further, the body 102 can include any desired material that is of sufficient strength to secure the canoe paddles. For example, the body 102 can be made of plastic, wood, metal or any other desired material.

By way of example, the body 102 can be between 10 inches and 14 inches long (i.e., in the direction that aligns with the shafts of the canoe paddles). In particular, the body 102 can be approximately 12 inches long. Additionally or alternatively, the body 102 can be between 3 inches and 5 inches wide (i.e., perpendicular to the shafts when secured). In particular, the body 102 can be approximately 4 inches wide. Proper dimensions are critical to ensure that the kayak paddle can be used in a normal manner and that the below advantages are obtained. The body 102 can allow sufficient overlap to prevent rotation of the paddle shafts relative to one another without being overly bulky which would increase the weight and discomfort of the user. Further, the body 102 can be sized to prevent rotation of the paddle blades relative to one another. I.e., the body 102 can be sized and shaped to prevent a feathering configuration other than the configuration intended. As used in the specification and the claims, the term approximately shall mean that the value is within 10% of the stated value, unless otherwise specified.

FIG. 1 also shows that the paddle converter 100 can include grooves 104. The grooves 104 are configured to receive the shafts of the canoe paddles. I.e., the shafts of the canoe paddles are secured in the grooves 104. The grooves 104 can prevent rotation of the shaft relative to the body 102. I.e., the grooves 104 can ensure that the shafts of the two canoe paddles remain straight or in line relative to one another when used as a kayak paddle. The grooves 104 can be internal (i.e., the sides are the same depth as the body 102) or can be external (i.e., the sides protrude from the body 102).

FIG. 1 further shows that the paddle converter 100 can include a first grip match 106a and a second grip match 106b (collectively “grip matches 106”). The grip matches 106 can be configured to match the grip of the canoe paddle. I.e., the grip matches 106 can be approximately the same size and shape as the grip of the canoe paddle. The first grip match 106a can be opposite the second grip match 106b along the major axis of the paddle converter 100.

FIG. 1 additionally shows that the paddle converter 100 can include a first strap 108a and a second strap 108b (collectively “straps 108”). The straps 108 can be used to secure the shafts of the canoe paddles within the groove 104. In particular, the first strap 108a can secure the first shaft and the second shaft to the body 102 in a first location and the second strap 108b can secure the first shaft and the second shaft to the body 102 at a second location. Two attachment locations can allows the shafts to remain in line in the desired configuration. One of skill in the art will appreciate that the two attachment locations can be replaced with a single long attachment location. I.e., if enough of the shaft is secured at a single location, then a single attachment will function equivalent to two attachment points. One of skill in the art will appreciate that the straps 108 can include any desired material and/or fasteners. For example, the straps can include a hook and loop fastener, buttons, snaps or any other desired fastener. Although straps 108 are used as exemplary herein, one of skill in the art will appreciate that any fastener configured to secure the shafts within the groves 104 is contemplated herein.

FIG. 1 moreover shows that the paddle converter 100 can include a first attachment 110a and a second attachment 110b (collectively “attachments 110”). The attachments 110 can secure the straps 108 in a fixed position relative to the body 102. In particular, the attachments 110 can ensure that the straps 108 are in correct position relative to the body 102. For example, the attachments 110 can include a rivet, slots, snaps or any other means for attaching the straps 108 to the body 102.

FIG. 2 illustrates an example a paddle converter 100 securing a first canoe paddle 202a and a second canoe paddle 202b (collectively “canoe paddles 202”) in a kayak paddle configuration. I.e., the first canoe paddle 202a and the second canoe paddle 202b can be used as a single double bladed kayak paddle.

FIGS. 3A and 3B illustrate a close up of a paddle converter 100 securing a first canoe paddle 202a and a second canoe paddle 202b. FIG. 3A illustrates a top view close up of a paddle converter 100 securing a first canoe paddle 202a and a second canoe paddle 202b; and FIG. 3B illustrates a side view close up of a paddle converter 100 securing a first canoe paddle 202a and a second canoe paddle 202b.

FIGS. 3A and 3B show that the paddle converter 100 is placed between the first canoe paddle 202a and the second canoe paddle 202b. The grip of the first canoe paddle 202a is lined up with the first grip match 106a and the grip of the second canoe paddle 202b is lined up with the second grip match 106b. The first strap 108a is then wrapped around the shaft of the first canoe paddle 202a and the shaft of the second canoe paddle 202b at a first location. The second strap 108b is then wrapped around the shaft of the first canoe paddle 202a and the shaft of the second canoe paddle 202b at a second location. One of skill in the art will appreciate that although an unfeathered configuration is shown, the paddle converter 100 can include a twist that allows the first canoe paddle 202a and the second canoe paddle 202b to be feathered relative to one another.

FIG. 4 is a flowchart illustrating a method 400 of securing two singled bladed canoe paddles to form a single twin bladed kayak paddle. In at least one implementation, the method can be implemented using a paddle converted, such as the paddle converter 100 of FIG. 1. Therefore, the method 400 will be described, exemplarily, with reference to the paddle converter 100 of FIG. 1. Nevertheless, one of skill in the art can appreciate that the method 400 can be used with devices other than the paddle converter 100 of FIG. 1.

FIG. 4 shows that the method 400 can include providing 402 a paddle converter. The paddle converter can include a body configured to structurally support a first canoe paddle and a second canoe paddle. I.e., the body provides a structural intermediary between the canoe paddles, converting them into a kayak paddle. In addition, the body can include a twist or curve that allows the paddles to be feathered relative to one another if the user so desires. Further, the body can include any desired material that is of sufficient strength to secure the canoe paddles. For example, the body can be made of plastic, wood, metal or any other desired material.

By way of example, the body can be between 10 inches and 14 inches long (i.e., in the direction that aligns with the shafts of the canoe paddles). In particular, the body can be approximately 12 inches long. Additionally or alternatively, the body can be between 3 inches and 5 inches wide (i.e., perpendicular to the shafts when secured). In particular, the body can be approximately 4 inches wide. Proper dimensions are critical to ensure that the kayak paddle can be used in a normal manner and that the below advantages are obtained. The body can allow sufficient overlap to prevent rotation of the paddle shafts relative to one another without being overly bulky which would increase the weight and discomfort of the user. Further, the body can be sized to prevent rotation of the paddle blades relative to one another. I.e., the body can be sized and shaped to prevent a feathering configuration other than the configuration intended.

FIG. 4 also shows that the method 400 can include aligning 404 the grip of the canoe paddles with grip matches on the paddle converter. The grip matches can be configured to match the grip of the canoe paddle. I.e., the grip matches can be approximately the same size and shape as the grip of the canoe paddle. The first grip match can be opposite the second grip match along the major axis of the paddle converter.

FIG. 4 further shows that the method 400 can include securing 406 the shaft of the canoe paddles in grooves on the paddle converter. The grooves are configured to receive the shafts of the canoe paddles. I.e., the shafts of the canoe paddles are secured in the grooves. The groove can prevent rotation of the shaft relative to the body. I.e., the grooves can ensure that the shafts of the two canoe paddles remain straight or in line relative to one another when used as a kayak paddle. The grooves can be internal (i.e., the sides are the same depth as the body) or can be external (i.e., the sides protrude from the body).

Securing 406 can include wrapping a strap around the first shaft of the first canoe paddle, the second shaft of the second canoe paddle and the paddle converter at a first location and wrapping a second strap around the first shaft of the first canoe paddle, the second shaft of the second canoe paddle and the paddle converter at a second location. The straps can be used to secure the shafts of the canoe paddles within the groove. In particular, the first strap can secure the first shaft and the second shaft to the body in a first location and the second strap can secure the first shaft and the second shaft to the body at a second location. Two attachment locations can allows the shafts to remain in line in the desired configuration. One of skill in the art will appreciate that the two attachment locations can be replaced with a single long attachment location. I.e., if enough of the shaft is secured at a single location, then a single attachment will function equivalent to two attachment points. One of skill in the art will appreciate that the straps can include any desired material and/or fasteners. For example, the straps can include a hook and loop fastener, buttons, snaps or any other desired fastener. Although straps are used as exemplary herein, one of skill in the art will appreciate that any fastener configured to secure the shafts within the groves is contemplated herein.

One of skill in the art will appreciate that the straps can be secured to body of the paddle converter using attachments. The attachments can secure the straps in a fixed position relative to the body. In particular, the attachments can ensure that the straps are in correct position relative to the body. For example, the attachments can include a rivet, slots, snaps or any other means for attaching the straps to the body.

One skilled in the art will appreciate that, for this and other processes and methods disclosed herein, the functions performed in the processes and methods may be implemented in differing order. Furthermore, the outlined steps and operations are only provided as examples, and some of the steps and operations may be optional, combined into fewer steps and operations, or expanded into additional steps and operations without detracting from the essence of the disclosed embodiments.
